This includes a risk that is continuously caused during use because it is virtually difficult to hold a fixing pin when the resident wants to replace the upper roller 301a during use.

In addition, as one of a series of processes for coupling the upper roller 301a to the conventional door frame roller support brackets 100a and 100 for a cabinet, the operator holds the body 110 while holding the fixing pin with the other hand. ), insert the fixing pin into the pin insertion groove 431 of the working body 430 constituting the locking operation member 400 shown in the long groove 114 for the pin operation provided on the rear side of the ), and then slide it in the left direction to lock it There is a process in which the locking projection 440 of the operation body 430 constituting the operation member 400 comes out of the through hole 111a of the partition film 111 .

At this time, when the operator inserts the fixing pin held by the other hand into the long groove 114 for pin operation and then applies a force to move it left and right, the sliding door 30 may shake left and right due to the applied force, so the operator Since it is not easy to work alone, there is also a problem in that another worker must perform the work while holding the sliding door 30 , that is, the work must be performed by two workers to be able to perform the work smoothly.

This problem is equally caused when the lower roller 301b is coupled.
